What is the furthest you can throw something?

In summary: I don't think this one is worth answering.Well if you look at it like that the answer with the longest distance wins.Thus the answer for Curl is unlikely to 'win'.

The power supply must be able to deliver large currents, sustained and controlled over a useful amount of time. The most important gauge of power supply effectiveness is the energy it can deliver. As of December 2010, the greatest known energy used to propel a projectile from a railgun was 33 megajoules.[6] The most common forms of power supplies used in railguns are capacitors and compulsators which are slowly charged from other continuous energy sources.
The rails need to withstand enormous repulsive forces during shooting, and these forces will tend to push them apart and away from the projectile. As rail/projectile clearances increase, arcing develops, which causes rapid vaporization and extensive damage to the rail surfaces and the insulator surfaces. This limited some early research railguns to one shot per service interval

Wait. That's a completely different question.

There have been experiments done to see of guns can be used to fire projectiles into orbit.

It's basically the same question.

What did the experiments conclude.

Rockets do not throw things, they carry a fuel/energy supply.

You can open it up to rockets if you like but I think it will be clear you can fire it a pretty much infinite distance.

Funny place to draw the line. It's as big a leap from firing to rocketing as it is from throwing to firing.

Depends on how you define throw, a throw implies release of the propulsion system.

As dave said there is no difference between a rocket and a rail gun from a propulsion point.

If I took a high speed camera view of the projectile inside a rail gun muzzle and slowed it down many thousands of times and played it back to you the sequence would look like a mass be propelled from a stationary start to a terminal speed.

The difference between the two events is the time to achieve both one looks like an explosive event the other doesn't simply based on our concept of timespan of the two events.

Have a look at the myth busters where they tried to pan cake a car it is done with a rocket sled but it looks like and explosive event (http://dsc.discovery.com/videos/mythbusters-compact-compact-rocket-sled-angle-3.html)

And as per dave's reasoning you could argue the LHC throw protons at almost the speed of light ... define throw please.

Question was misunderstood apparently.

Question is extremely poorly written.

Now you're assuming there's no mountains in the way? Non-sense. They are a factor in throwing far, even if it's unrealistic.

Here is how poorly formed your question is, when asking Guinness World Records for the "farthest throw", here is what it spits out:

http://www.guinnessworldrecords.com/Search/rdb.aspx?q=largest+OR+fastest+OR+smallest+OR+longest
Farthest throw of a playing card

Farthest throw of a person

Farthest washing machine throw - individual

Farthest hammer throw (female)

Farthest washing machine throw - pair

Farthest mobile phone throw by an individual (male)

Farthest light bulb throw

Farthest water balloon throw

Longest hammer throw on Mario & Sonic at the Olympic Games (Wii)

Longest peanut throw

You can 'refine' the search with "longest", "farthest", "furthest" etc to get even more results.

You could also look up the olympic records as well.

There are so many factors involved that it's non-sense.

Personal strength, size, the object, the weather, the Earth's surface etc, etc, etc.

Just to add, didn't Sadam try to build a massive gun that could fire projectiles hundreds of km?

I went to museum in England that had a section of it on display. Customs caught it before they were able to dispatch it.

If you are in deep space, and you throw something in an appropriate direction, it will travel forevermore. Of course you will also travel indefinitely in the opposite direction.

Is this meant to be a biophysical question? I.e. what is the furthest a human being is capable of throwing X object based on the limitations of the human body?

Without disambiguation I can safely say things like this:
I once threw some saliva 200m (from the roof of a building)
I once threw a bullet at least 1km (from a gun)
I once threw in the towel (how far? all the way)
I once threw a hissy-fit (again, it went all the way)
I once threw my wallet into the future (it's still going)
I once threw a golf ball 200m (from the golf club)
I once threw a rock and hit France (from Paris)
I once threw a cricket ball 60m (I did)
I once threw someone miles away off guard (over the phone)

The question "what's the furthest you could throw something" needs to be defined so that we have
A something to measure by (baseball? feather?)
A method of throwing (why include guns?)
A place of throwing (of a bridge? mountain? ISS?)
Who are we talking bout (me? mankind?)

It's the furthest you can throw something on earth.
You can choose your object but I an interested in the one throw the furthest.

Hope that clear it up!

No there is a clear and obvious difference between a rocket and a gun, a rocket carries it's own energy source or fuel supply a gun doesn't. A gun fires a projectile and relies on the kinetic energy of the projectile alone.

In that case I can throw a weather balloon thousands of km around the Earth. Or I could build a Lofstrom loop and throw a car into orbit. Or I could throw my mate 8km off of Mt Everest.

This really does seem a bizarre topic to be asking about. Without specific qualifiers to an outrageously ambiguous question this doesn't belong in this forum.

Yes, just as there is a clear difference between throwing an object manually and firing it with technology, yet you include them in the same question as if they're the same.

How are we to judge where you decide to draw the line between what qualifies and what does not?

Not to mention the clear differences between objects and the condition where you throw them! (Baseball off of a building or boomerang in a forest?)

Not really you are using the weight of the atmosphere to power it so it is not a throw as such.



When you know the answer the question is not ambiguous.

It's only a bizarre topic if you choose to be awkward about it.

No there is no real difference between throwing and firing it, a throw implies that the kinetic energy of the projectile is the only source of energy, so there is no difference between manually and using technology in reality, they are both throws.
If you choose to pick only manual throws then that is a poor effort on your part.

AtomicJoe, instead of answering all these individual posts trying to explain why they do / do not apply to your idea in your head, tell us the idea you have!

Give us a clear and precise question. It will save time and thread space. All you're doing now is boosting post counts.

Otherwise, this thread remains complete non-sense and I can't see it remaining open much longer.

If I throw a paper airplane the atmosphere is helping "power" it.

You are clearly a troll who is just wasting the time of everybody involved, this thread should be locked.

These are distinctions you are making as you go. We have been asking for clarification but you won't provide it. when people give valid answers, you rule them out based on criteria that you reveal as it pleases you.

Troll is a bit harsh, IMO.

If he asks a question and we don't want to play, we don't have to play.

However, this is not a well-formed physics question, and the OP is clearly revealing criteria as it suits him to get to the answer he wants.

It's really a riddle.

It does not belong in the physics forum. I am going to have this moved to GD.

Look at his other thread on shortest distance.

Nothing better than a troll for sure.

It is a serious question and a good one.

It is also a tough question, which is why nobody can give a definitive answer.

I have qualified the question a number of times for those who cannot see it for what it is.

We can't answer you because you keep changing the criteria.

We can't answer because you haven't defined exactly what you want an answer for.

It is one of the worst questions put out there.

Yes it is under certain circumstances, it is getting lift from rising air (usually hot air).
I am talking about something powered solely by it's own momentum after release.

Thank you. You do have your own idea of the one correct answer.

This is a riddle.

You could have told us that up front so we could have taken it in the light is was intended.

Though I might not have used the term 'troll', you do seem to be delighting in the feeling of pulling everyone's strings.

Perhaps Troll was harsh I admit. I also see this is a waste of time, it's not a riddle nor is it a serious question. It should be moved out of the general physics section for sure, good call.

Perhaps you should clarify one last time then because you've failed to explain what you hope to achieve. Are you looking for a specific answer? Are you looking for the theoretical maximum? What are you parameters? If you are including guns then the furthest I can throw anything is infinity.

It is not necessarily generating lift from air however its aerodynamic shape allows it to travel further in atmosphere compared to an identical piece of paper that is scrunched into a ball.
